Many years ago, I had a '69 Road Runner that had black vinyl mats (black carpeting in car) that were ribbed and had an embossed Pentastar logo on top; they also had lettering embossed next to the Pentastar, something like "Chrysler Corp" but I can't recall exactly. Unfortunately I was never able to contact the original owner to see if they were assembly-line or dealership, but as I recall they seemed like something that had come from a dealership Parts Dept.
